Your Skin Type: Oily

Your main goals: Keep pores clear, and don’t overdry, which can result in rebound greasiness. But don’t forgo moisturizing products—just be sure they won’t cause blemishes.

Cleanser

For a deep clean, wash morning and night. Consider using a power brush, says Elizabeth Hale, a New York City dermatologist. The latest versions come with pads infused with salicylic acid cleanser to stop breakouts.

To buy: Neutrogena Wave Sonic Power-Cleanser, $16 at drugstores.

Oily: Day Lotion

Although your skin might not require much extra moisture, it does need the protection of a broad-spectrum sunscreen year-round. Look for an oil-free lotion with SPF 15.
